Type 1a endoleak following Zone 1 and Zone 2 thoracic endovascular aortic repair: effect of bird-beak configuration†

Abstract

Appropriate stent grafts need to be chosen carefully to prevent Type 1a endoleak and bird-beak configuration after landing Zone 1 and 2 TEVAR. Patients with bird-beak configuration on early postoperative multidetector computed tomography require closer follow-up to screen for Type 1a endoleak.
